A follow-up to my previous blog entry on Exchange 2007...if you've bought earlier versions of Exchange you've undoubtedly taken comfort in the fact that a Client Access License (CAL) for the comparable version of Outlook.  That's changing with Exchange 2007 -- an Exchange 2007 CAL does not include a license for Outlook 2007, you'll have to buy that separately.  There are some exceptions for Software Assurance customers.

Unlike prior versions, Exchange Server 2007 Standard or Enterprise does not include the right to install Outlook on devices for which CALs are obtained. (http://www.microsoftvolumelicensing.com/userights/ProductPage.aspx?pid=111)
